PP servo and ZO Shot in the dark!

edited February 2010 in Technique & Theory
Looking at upgrading my 02 to ZO but hitting some big problems. Was it my imagination a few years back that ZO advertised that a mechanical version ZO was in the works? This disappeared right after the lawsuit agreement? Was it possible that ZO was proposing to use a PPlike servo? I have some avionics guys at work that say a digital to mechanical is not only possible but has already been done in the DC-9 aircraft engine fleet. Obviously a company could not use the PP servo but an individual could for his own use apply it. Anyone out there reverse engineer one yet? Email me at: thager10 at hotmail dot com or whisper if you don't want to comment on this board. I'm half tempted to throw some money at it and I think I have the people that could pull it off.
Stir vigorously then leave!

    First of all, that PP "servo" motor is actually a 1.8 degree <strong>stepper </strong>motor, and these are readily available on eBay, along with many other discount sources.  In fact, here's one now:  http://cgi.ebay.com/TAMAGAWA-STEPPER-STEP-MOTOR-with-REAR-SHAFT-150oz-in_W0QQitemZ260490710807QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3ca674cf17

    Controlling it and coordinating it through some sort of I/O (input/output) drive unit is not difficult; I would think an algorithm utilizing simple step and direction commands would suffice.  A very dependable driver for this stepper can be found here: http://www.geckodrive.com/ and a discussion or two with Morris would probably be extremely helpful, though you should be prepared to be overwhelmed a bit by tech talk.

    If you want to discuss it further we can do so privately - pretty sure you already have my email.

    Thanks TW. You put what the avionics guys told me into plain language. I'll get ahold of you later when I have more figured out. There is one expert in this field we want to get input from before we continue.

    Bit the bullet and am going with ZO conversion. Turns out my 02 has everything needed for e-control.

    Bummer! Well, good for you Thager, but I was looking forward to reading about the servo conversion.

    I was looking forward to reading about servo conversion, too. Anyone else taking up this project?

    I would love a way to get ZO in my 2002 Malibu.  I don't have the extra cash to upgrade right now.  My wife thinks college savings are more important.
